Freezer ***** choice

[jakb21599]

What would be the pro's and con's of using R22 for a freezer ? I have a customer that wants to use R22 because it is cheaper than 408A I am having to change his condensing unit out because the coil is leaking and can't be fixed so he lost all his ***** . So he wants to go back with R22 because of the cost saving of using 22 instead of 408. Do you guys know of any freezers that run off of R22 ? I have not came across any. I know the compressor oil will have to be changed and the txv power head and orfice. Any suggestions or reason on this issue ? Thanks for your input
